Septic arthritis

I was admitted for extreme pain in September last year with septic arthritis in my spine. I had never heard of it, despite being a nurse for 34 years. I was septic with a temperature of nearly 40. I apparently had infective endocarditis which had traveled to my spine. I was in hospital for three weeks and my right nip also became infected I have been on Ibtravenous and oral antibiotics for three months and off them just over a week before it moved to my right knee . I have had a further weeks oral antibiotics course. My knee is awful at the moment very swollen and painful despite the concoction of pain killers I take. Any advice gratefully appreciated ❤️
